Roku today announced the introduction of SoundBridge Radio, a wireless (Wi-Fi) music system. With a traditional tabletop radio form factor, SoundBridge Radio combines stereo speakers with a subwoofer, AM/FM radio, alarm, and Internet radio and digital music streaming features into a single, compact component. The new radio includes all of the traditional features of SoundBridge as it can access playlists from both Mac- and Windows-based computers, and support music streaming in MP3, WMA, AIFF, WAV and un-protected AAC formats. SoundBridge Radio will sell for US$399 beginning in early November, and customers who order before October 31 will receive a $50 discount.
